Description

Badminton service device

Technical field

The utility model relates to a kind of sports apparatus technical field, especially a kind of badminton service device.

Background technique

As the idea of " movement can promote human body healthy " deepens continuously the popular feeling, masses of the shuttlecock as a par Sports events has been more and more people to accept, for taking exercises and wearing down free time.Now mainly have three in the market Class shuttlecock transmitter:

One kind predominantly friction service.Its primary structure is to drive two PU to take turns high speed rotation by two motors, works as ball Head when entering between two-wheeled, ball is quickly issued by squeezing.Although the serving way meets transmitting on range It is required that but the radiation pattern is easily damaged shuttlecock, reduce shuttlecock access times, and due to the limitation of self structure, should Transmitter can not achieve full automation, and the realization needs of certain functions manually adjust.

One kind is served for motor pendulum.Its primary structure is to drive a bat to rotate using motor, and sphere is put in advance On some point of rotation path, when bat reaches this, ball is just gone out by beating.This kind of height to ball launch angle controls And service of being swung left and right then seems helpless, cannot reach people well for the demand of training mate.

One kind is pneumatic service.Its primary structure is to be blown out sphere according to both fixed tracks using high pressure gas, to ball Far and near and angle has certain control ability, but due to needing high pressure gas, so needing high-pressure cylinder, and is equipped with multiple electricity Source, system is more, and volume is more huge, is not suitable for outdoor shuttlecock place, at high cost, is not suitable for general population, is not achieved General population utilizes the purpose of its body-building.

The above three classes badminton service robot device can not include all service and regulatory function, be not suitable for accompanying as people Practice, and some are there is also at high price or volume is larger, is not suitable as the private purchase article of consumer.In order to allow people Can more facilitate quickly practice shuttlecock in daily life, it is necessary to one kind not only can satisfy each orientation, each height The service of degree, and it is suitable for individual, external form has the full-automatic badminton service robot device of higher artistic value again.In " human nature Under the expediting the emergence of of change " theory, a new automatic badminton service robot device replaces those heavy inefficient service robots to become development Trend.
